Dear everyone commenting on every article about big boobs on any blog (other than blogs specifically about lingerie fitting),
DD is a relatively small cup size, unless perhaps you have a 40 inch back. If you think you’re a DD, you either have smallish boobs, or you are wearing the wrong size.
DDD seems to be used as a general term to mean “anything over a D cup, which is spilling horribly over the cups of the ill-fitted bras I am forced to buy at department stores because I’ve never been properly fitted and have no idea what size my boobs really are.” Maybe work on that, ladies.
PS. DDD isn’t even a real cup size. It goes from DD to E.
